Safety notices
5TGR2050 Series Instruction Manual
Safety notices
This instrument is:
·A safety Class I instrument according to IEC classification and has been designed
to meet the requirements of EN61010-1 (Safety Requirements for Electrical
Equipment for Measurement, Control and Laboratory Use).
·An Installation Category II instrument intended for operation from a normal
single-phase supply.
·Tested in accordance with EN61010-1 and has been supplied in a safe condition.
·Designed for indoor use in a Pollution Degree 2 environment in the temperature
range 5°C to 40°C, 20% - 80% RH (non-condensing).
WARNING
Do not operate while condensation is present.
Do not operate outside its rated supply voltages or environmental range.
THIS INSTRUMENT MUST BE EARTHED.
Any interruption of the mains earth connector, inside or outside, will make the
instrument dangerous. Intentional interruption is prohibited.
Any adjustment, maintenance and repair of the opened instrument under voltage
must be avoided.
When connected, terminals may be live and opening the covers or removal of parts
(except those that can be accessed by hand) may expose live parts.
To avoid electric shock, or damage to the instrument, never allow water to get inside
the case.
If the instrument is clearly defective, has been subject to mechanical damage,
excessive moisture or chemical corrosion the safety protection may be impaired and
it must be withdrawn from use and returned for repair.
This instrument is protected by an internal fuse which is not user serviceable.
This instrument uses a Lithium button cell for non-volatile memory battery back-up;
typical life is 5 years. In the event of replacement becoming necessary, replace only
with a cell of the correct type, i.e. 3V Li/Mn0220mm button cell type 2032.
Exhausted cells must be disposed of carefully in accordance with local regulations;
do not cut open, incinerate, expose to temperatures above 60°C or attempt to
recharge. Refer to ‘TGR2050 Service Guide’ for further details.
CAUTION
Do not wet when cleaning, use only a soft dry cloth to clean the screen.

2 - Installation
Mounting
6TGR2050 Series Instruction Manual
2.INSTALLATION
Mounting
This instrument is suitable for bench use and rack mounting.
For rack mounting the protective bezels and handle/stand should be removed such
that the instrument can be fitted beside any other standard 2U half-rack instrument
in a 19” rack. A suitable 2U 19” rack kit is available from the manufacturers or their
overseas agents.
See rack mount instructions for details on how to remove the protective bezel and
handle.
Ventilation
The instrument uses a fan fitted to the rear panel. Take care not to restrict the rear
air exit or the inlet vents at the front (sides and underneath). In rack-mounted
situations allow adequate space around the instrument and/or use a fan tray for
forced cooling.
Handle/stand
The instrument is fitted with a 4-position handle/stand. Pull out both sides of the
handle at the case pivot points to free the position locking pegs and rotate the
handle from the stowed position to the required stand or handle position. Release
the sides of the handle to lock it in the new position.

3 - Electrical Requirements
Mains operating voltage
7TGR2050 Series Instruction Manual
3.ELECTRICAL REQUIREMENTS
Mains operating voltage
This instrument has a universal input range and will operate from a nominal 115V or
230V mains supply without adjustment. Check that the local supply meets the AC
input requirement given in the Specification.
Mains lead
Connect the instrument to the AC supply using the mains lead provided.
Should a mains plug be required for a different mains outlet socket, a suitably rated
and approved mains lead set should be used which is fitted with the required wall
plug and an IEC60320 C13 connector for the instrument end.
To determine the minimum current rating of the lead-set for the intended AC supply,
refer to the power rating information on the equipment or in the Specification.
WARNING
THIS INSTRUMENT MUST BE EARTHED.
Any interruption of the mains earth conductor inside or outside the instrument will
make the instrument dangerous. Intentional interruption is prohibited.
Before use, inspect provided mains lead for any signs of damage. Do not use if lead is
damaged.
Before use, inspect the instrument for any signs of damage. Do not use if damaged.

-Trigger key
TRIGGER key is used to issue a manual trigger signal.
⑤Numeric keypad
Numeric keys permit direct entry of a value for the parameter currently selected.
⑥RF Output Port
This is a 50ΩN-type output socket. The maximum output is 1Vrms (+13dBm) into
50Ω. It can tolerate a short circuit indefinitely. Protected against accidental
connection of up to 50VDC.
NOTE
The N Type connector is a precision component that should be protected z excessive
wear to ensure that its RF characteristics (impedance and VSWR) are accurately
maintained. If the instrument is used in a manner that demands many
connections/disconnections to and from the RF OUT it is good practice to fit a male–
to–female adaptor to the socket which can be replaced periodically.
CAUTION
Do not apply external voltages to the RF output port.
⑦RF output key
The OUTPUT key switches the RF Output Port on or off. The key becomes illuminated
when the output is on.
⑧Escape Key/ Local
Entry can be abandoned at any point by pressing the escape key, this key will also
exit the selection or screen currently selected. Additionally, when in remote mode
this key is used to return the instrument to local operation.
⑨Directional keys
The direction keys are used for navigating parameter windows, scrolling numeric
parameter values and selection lists, additionally these keys are used to apply step
changes to the frequency and amplitude.
⑩Rotary knob
The rotary knob is used to navigate the user interface, it features a ‘press’ function to
select an option. See ‘Rotary knob principles’ for more details.

7.GETTING STARTED
Using this manual
This section is a general introduction to the organisation of the instrument and is
intended to be read before using the instrument for the first time.
In this manual front panel keys and sockets are shown in capitals, e.g. FREQ, AMP,
MOD; Text, entry fields and messages displayed on the LCD are shown in a different
font, e.g. Frequency, Amplitude.
The descriptions in this manual relate to using the instrument via the touch screen,
alternatively; the hard keys and rotary knob can be used. The TGR2050 Quick Start
Guide provides concise instructions on how to use the instrument via alternative
methods; it is recommended that this is read first and is available to download from
www.aimtti.com/support
A separate programming manual is also available to download from
www.aimtti.com/support.
Switching on

8.NAVIGATION CONTROLS
Overview
The versatile user interface can be navigated using the touch screen, knob, front
panel keys or a combination of them all.
Many settings can be made more quickly and easily using the touch screen alone;
the rotary knob is most useful when, for example, a parameter is being frequently
varied during manual testing, see ‘Rotary knob principles’ section.
Both buttons and parameter windows are described in this manual. A button ①will
directly select or apply the action; parameter windows ②will give a range of
options.
